You want to get REALLY good at AWS and Terraform?
Just go and delete a few resources in AWS that are knotted up with a bunch of others - then try to untangle the mess without just wiping the account.
Honestly - I wasn't happy that I got into the mess that I was (mostly due to RDS instances not actually being able to update the way TF was claiming they would), but I learned a bit and have a much better understanding of the TF CLI now.
In other news: anyone know of upcoming TF replacements? :-)
